Genuine HP 826A Black Toner Cartridge

The HP CF310A is an original LaserJet toner cartridge supplying black output for high-volume office printing. It is built for workgroups that produce large numbers of text-heavy documents and need dependable single-cartridge replacement.

Consistent output across long print runs

Rated at approximately 29,000 pages, the cartridge maintains crisp black text from the first sheet to the last without the fade or streaking that can appear with non-genuine supplies. Operating between 59 and 81 °F and 10 to 70 % RH, it delivers steady performance during sustained daily workloads.

Designed for HP LaserJet M855 Series

The cartridge fits directly into compatible M855 printers with no adapters or firmware workarounds required. HP Web Jetadmin integration lets administrators monitor toner levels remotely, reducing unexpected downtime. Offices needing colour output or lower page volumes should choose a different cartridge.
